Abstract
A security element including: a plurality of focusing elements, a plurality of image regions where each image region is associated with a focusing element, each image region is printed with at least two layers, the first layer is offset by a first predetermined amount from a reference axis in the image region, the second layer is offset by a second predetermined amount from a reference axis in the image region, each layer being in different colors, and each image region includes at least a first and second sub-region, wherein a first image is formed in a first range of viewing angles from the first sub-region and a second image is formed in a second range of viewing angles from the second sub-region.
Claims21
A security element including:
- a plurality of focusing elements,
- a plurality of image regions where each image region is associated with a focusing element,
- each image region is printed with at least two layers,
- the first layer is offset by a first predetermined amount from a reference axis in the image region,
- the second layer is offset by a second predetermined amount from a reference axis in the image region,
- each layer being in different colours, and
- each image region includes at least a first and second sub-region, wherein a first image is formed in a first range of viewing angles from the first sub-region and a second image is formed in a second range of viewing angles from the second sub-region.
A method of forming a security element including the steps of:
- providing a transparent or translucent substrate,
- applying a plurality of focusing elements to a first surface of the transparent or translucent substrate,
- applying a plurality of image regions to the opposite surface of the substrate with at least two layers,
- wherein the first layer is offset by a first predetermined amount and the second layer is offset by a second predetermined amount from a reference axis in each image region,
- each layer is printed in different colours and wherein
- each image region includes at least a first and second sub-region, wherein a first image is formed in a first range of viewing angles from the first sub-region and a second image is formed in a second range of viewing angles from the second sub-region.
